* made names of distro module consistent across OpenSLX - now the always start with

  a capital letter followed by all lowercase (Debian, Fedora, Gentoo, Suse, Ubuntu)
* refactored loading of distro modules into a separate function (loadDistroModule() 
  in Basics.pm)
* finished support to logging to a file in syslog plugin
* worked at desktop plugin (still not working, though)
